Overview

The HOBOnet Wireless Temperature and Relative Humidity Sensor provides a cost-effective and scalable solution for web-enabled monitoring of air temperature and humidity. HOBOnet Wireless Sensors communicate data directly to the HOBO RX3000 or the HOBO MicroRX station, or pass data through other wireless sensors back to the central station. They are preconfigured and ready to deploy, and data is accessed through HOBOlink, Onset's innovative cloud-based software platform.

 

Sensor Features

  • High accuracy: ± 0.2°C (± 0.36°F) and ± 2.5% RH 
  • Robust RH sensor withstands extended use in high-humidity environments

Wireless Features

  • 900 MHz wireless mesh self-healing technology
  • 450 to 600 meter (1,500 to 2,000 feet) wireless range and up to five hops
  • Up to 50 wireless sensors or 336 data channels per HOBO RX station
  • Simple button-push to join the HOBOnet wireless network
  • Onboard memory to ensure no data loss
  • Powered by rechargeable AA batteries and built-in solar panel
